'FRAN Z MUSIL EDLER To all whom it may concern:

Bekit known that I, FRANZ MUSIL EDLER- VON MOLLENBRUCK, a subject of the Emperor of Austria, residing at Linz-on-the-Danube,

- have invented new and useful Improvements l following is a specification.

of a cement which imparts I o from it a high resistance to bending.

For the manufacture of my cement good 'Portland cement or a sin 'lar mortar-former is mixed with fibrous material and the mixture ground in suitable apparatus. rience has shown that the mere mixture of Portland cement and brous mam n e co any in imate mixture e ween the two substances. 'able inclination to adhere to one another, and :0 this characteristic is not overcomeby merely them with cement, so that it is not ossib e to obtain a homogeneous fine tribution of the fibers in the cement. This result can only be attained by simultane- 2 5 ously gg'adig the materials inia' lii'fftlie' i ers are no yet separated with the cement. In this way the individual fibers are laid bare and inclosed in cement-dust and do not adhere or conglomerate. The fibrous cement made as above described is manipulated in the ordinary way.

The process forming the subject of this invention differs from the usual method of addin to cement fibrous materials-such as la wool and the 5 as estos cellulose s a that t'l'ie EBrous substances are not only mixed together loose, but at the moment of their being separated out are surrounded by .5 i-e UNITED STA ES PATENT OFFICE.

and cement in a mill; but this process possesses the disadvantage-that large quantities of water are necessary, an be used immediately after Such cement cannot be manufactured in the Manufacture of Cements, of which the stoc d the mixture must its manufacture.

. s In lieu of mixtures of Portland cement an This invention relates to the manufacture fibrous materials I ma intimately rind to objects made mixtures of fibrous materlals Blast-iii'nace s a an ca cmed lime. I'lns mixture is less ura e; ut articles made therefrom possess strength which is equal to that of articles made from Portland cement and fiber Having now particularly described and ascertained the nature otmy said invention 5 and in what manner the same is to be performed, I declare that what I claim is- 1. The method of manufacturing cement consisting in first mixing cementitious material with fibrous material and then grinding said mixture whereby a more intimate mixture of the cementitious and fibrous materials is secured, substantiailfy as described.

2. The method of man acturing cement consisting in first mixing cement with a fibrous material and then grinding said mixture, whereby a more intimate mixture 0 cement and fibers is secured, substantially as described.

3. The method of manufacturing cement, consisting in first mixing .ement with a fibrous material and then grin said mix ure w ere y said ingredients are more intimately mixed, substantially as described.
